Monroe Shocks & Struts 66437 Product Description

Monroe Magnum 66437 Amortiguador de Dirección

Key Features

  • Robusto bloqueo hidráulico: Evita la extensión excesiva de la suspensión, el tope del pistón y evita daños en el conjunto del retén (en la mayoria de aplicaciones)
  • Cojinete recubierto de PTFE: Reduce la fricción durante el funcionamiento entre la barra y la guía de la barra, mejorando la durabilidad - en la mayoria de aplicaciones
  • Bujes con rebordes Tenneco: Bujes con rebordes y bujes adheridos con diseños de manguito que evitan la salida del buje para mejorar la calidad y la durabilidad, en la mayoría de las aplicaciones
  • Cargado con gas nitrógeno: Para una mejor conducción y manejo, ayuda a mantener el contacto de la llanta con el suelo al reducir la aireación - en la mayoría de las aplicaciones
  • Técnica de soldadura en bucle: La soldadura por resistencia con soldadura adicional de 360 ​​grados proporciona hasta 13,100 libras (6.395 kg) de resistencia a la tracción para una máxima durabilidad (cuando se requiera)
  • Tubo de reserva de 2 pulgadas (50,8 mm) o 2-1/4 pulgadas (57,2 mm): Más líquido para un rendimiento más uniforme - cuando sea necesario
  • Diámetro de 1-3/8 pulgadas (35 mm): Diámetro más grande que la mayoría de los amortiguadores para brindar un control más eficiente y consistente, en la mayoría de las aplicaciones
  • Vástago de pistón de 5/8'' (16 mm) de diámetro: Diseño nitrocarburado ecológico, mantiene los beneficios del cromo, sin afectar la durabilidad. El uso de hierro sinterizado permite dimensiones de pistón precisas para un ajuste excepcional
  • Tubo de presión de .05 pulgadas que soporta una presión de 9 KPSI
  • Válvula de 10 etapas: reacciona a una amplia gama de condiciones de conducción, en la mayoría de las aplicaciones
  • INSTALLERS ADVANTAGE -- Designed to save time, simplify the job, fix OE design issues, solve customer complaints or enhances durability and longevity
  • FOR HARDWORKING COMMERCIAL VEHICLES   -- Designed to handle the demands of high mileage and severe use class 3-6 trucks and buses
  • CONSISTENT RIDE -- All-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while 2-in. or 2-1/4-in. reserve tube holds more fluid to improve performance (when required)
  • EXCEPTIONAL HANDLING -- 10-Stage valving, tuned specifically to each vehicle, adjusts to road extremes while the larger 1-3/8-in. bore provides more efficient damping control to provide consistency and a smooth ride (most applications)
  • STRONG AND DURABLE -- Shouldered bushing and bonded bushing with sleeve protects from bushing walkout for improved quality; arc welds up to 360° for durability
  • BUILT TO LAST -- Robust hydraulic lock-out prevents over extension of air bags, top-out of the piston and averts damage to seal assembly (on most applications)
  • LONGER SERVICE LIFE -- Bearing with PTFE coating reduces friction between rod and rod guide combined with nitrocarburized piston rod provides durability and longer service life (most applications)
  • REDUCED NOISE, VIBRATION AND HARSHNESS -- Delivers exceptional control and isolates impact-related noise, vibration, and harshness under most driving conditions
  • IMPROVES PERFORMANCE -- Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
  • BUY WITH CONFIDENCE -- Comes with Monroe’s 90-day Risk Free Ride Offer and Limited Commercial Warranty

El amortiguador Monroe® Magnum ™ para vehículos de clase 3-6 esta cargado con gas para una respuesta más rápida y una conducción estable y más cómoda.

    Lined up perfectly with the original. Install took about an hour with the right press. Solid feel back in the steering, no more clunk over bumps.

  • Shipped fast across Canada
    Jen P.Verified BuyerMay 14, 2026

    Ordered on a Monday, had it by Wednesday in Calgary. Greasable fitting is a nice touch. Quality looks on par with OEM.

  • Good part, double-check your side
    Steve R.Verified BuyerApr 30, 2026

    Works great so far. Just confirm fitment for your exact trim before ordering — the fitment list on the page was accurate for mine.

  • Quiet again
    Amrit S.Verified BuyerApr 19, 2026

    Replaced both sides at the same time. The knocking noise is completely gone. Boot quality feels durable.
